A Prometheus exporter for Emporia Energy smart devices.

This repo contains a Python-based Prometheus metric exporter for Emporia smart devices. This can then be combined with Grafana for dashboard viewing. Note that the default port used (9947) has been reserved on the Prometheus Wiki.

Place a file called .user.json in the base directory of this repo. It should contain the following:

{
    "username": "<Emporia Username>"
    "password": "<Emporia Password>"
}

See the pypi entry for the PyEmVue module for more information. Then run the following command:

./emvue-exporter.py

If you point a browser at localhost:9947 you should see the metrics for the Emporia devices linked to your account. For more usage options:

./emvue-exporter.py -h
